Introduction to Linux - A Hands on Guide

This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I have searched the forum for similar problems. These errors are beyond my understanding. There are some problems with more than one copy of header files. However, I don't know which one I should have, and what might be an old one.

The system was recently upgraded from 14.0 to 14.1. I did a full install. I had a long list of sbopkg's to upgrade. All have worked, except guvcview, and tesseract. The errors in tesseract are similar, however, different .h files are mentioned.

Right now I would like to fix guvcview, and understand what is wrong with it. Then work on tesseract.

An update. I have compiled guvcview on my laptop, copied the sbo package on to the failing system and installed the update. I did the same with tesseract. Both programs are now at the levels listed in slackbuilds for 14.1.

The laptop I compiled the programs was a clean install, I had partitioned the disk, and formatted, installed, and the slackbuilds run.

On the failing system, I had upgraded from 14.0; so now I think the problems were caused by some old files left around, that were not updated or replaced with the upgrade process.
